Hey just to put some info out there for my fellow gear heads... There is a place here in Chicago that is fairly cheep and has a good rep for drivetrain parts as well as labor. I am having them redo my 9" rear to a locker with 4:11's for about $660.00 that is new bearings and all. I just have to take to them, and reinstall it.
